' VEHICLE- SPRING.

SPECIFICATION forming part of Letters Patent No. 234,964, dated November30, 1880.

Application filed August 12, 1880.

To all whom it may concern Be it known that I, WESLEY COLE, a citizen ofthe United States, resident at Rochester, in the county of Olmsted andState of Minnesota, have invented certain new and useful Improvements inVehicle-Springs; and Ido hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

This invention has relation to vehiclesprings; and it consists in theimproved fea tnres of construction and combination hereinafter fullydescribcrhand particularly pointed out in the claims.

Figure 1 is an end elevation of a port-ion of a vehicle having myimproved spring applied. Fig. 2 is a sectional side elevation of thesame. Fig. 3 is a perspective view of one of the springs detached. Fig.4 is a perspective of one of the eye-clips for securing the lower end ofthe spring to the bolster. Fig. 5 is an end elevation of aportion of avehicle, showing a modification of my spring. Fig. 6 is a sectional sideelevation of the same. Fig. 7 is a perspective view of the angle-platefor securing the upper end of the modified spring, and Fig. 8 is a planview of one of the modified springs.

Referringby letter to the drawings, A designates the bolster, B thereach, 0 the stakes, and D the lower frame or portion of the box of avehicle.

E designates one of my improved springs, formed of round steel wire ofappropriate size, bent first at the middle of the piece of which thespring is formed, back nearly upon itself, and the arms thus formed bentto form corresponding U-shaped bends, as clearly shown in Fig. -3 of thedrawings. Two of these springs are employed upon each'bolster, and aresecured to the bolster by eye-clips F, bolted to the bolster near thestakes, as shown. The points G of the springs E enter the eyes H of theeye-clips.

(No model.)

The upper ends of the springs E are secured to the under faces of thecross-pieces I by staples J, driven at the angular or V-shaped bend inthe springs. The cross-pieces I are notched in each end to receive thestakes O, and play up and down upon the stakes when the springs areactuated by a load.

The modification of the invention shown in Figs. 5, 6, 7, and 8 isexplained as follows: The springs K are of flat metal, notched in eachend to receivethe bolts L, and bentin U-formed folds or bends, asplainly shown in the drawings. Their lower ends are secured to the upperfaces of the bolsters by clip-bolts M and the bolts L. Their upper endsare secured to the under faces of tlanges N upon angle-plates O, securedto the under face of the box D at its ends. Clip-bolts M and bolts L areused to secure the upper ends of the springs K to the flanges N, asshown.

The stakes guide the springs so that they have neither lateral norhorizontal play, but have a vertically-yielding motion only. Thestaple-connection at the top receives no great strain, as the weightcomes upon the spring itself, and the staple is only necessary toprevent the cross-piece from leaving the spring in the event of aviolentjolt.

The construction is cheap and simple, and the springs are durable.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isi 1. The combination of thebolster A, having the stakes O, the notched cross-piece I, and thesprings E, eye-clips F, and staples J, constructed and operatingsubstantially as and for the purposes set forth.

2. As an improvement in vehicle-springs, the spring E, of round wire,having the V- shaped and U-shaped bends, secured to the vehicle by theeye-clip F and the staple J, substantially as and for the purposes setforth.

In testimony whereof I affix my signature in presence of two witnesses.
